Helty FlowULTRA (Enthalpy) Decentralised Heat Recovery Unit | Compact wall ventilation System

Helty FlowULTRA (Enthalpy) Wall-Mounted MVHR Ventilation Unit A high-capacity decentralised wall-mounted MVHR unit from the Italian manufacturer Helty. Equipped with a high-efficiency enthalpy counter-flow heat exchanger, it ensures continuous dual-flow air exchange with up to 88% thermal energy recovery while maintaining natural indoor humidity levels. Designed to serve medium-to-large living spaces, small offices, professional practices, and open-plan areas. Features advanced multi-stage filtration (ePM2.5 65% / F7) that captures pollen, fine dust, smog, and allergens for cleaner indoor air. Core Advantage: Maximum Comfort, Smart Control, and Quiet Operation High-Capacity Ventilation Performance: Increased airflow rate up to 120 m³/h with 4 operating speeds + Night mode + Hyperventilation mode. Minimal Structural Impact: Clean installation without requiring bulky ductwork throughout the room—only requires drilling two small 100 mm diameter holes through the exterior wall (2x Ø100 mm). Enthalpic Heat & Moisture Recovery: Counter-flow enthalpy heat exchanger recovers up to 88% of thermal energy while maintaining optimal indoor humidity, preventing dry indoor air in winter and eliminating mould risk. Smart Control & Monitoring: Automatic indoor climate management via an integrated hygrometric sensor (humidity sensor), Helty Home mobile app (Wi-Fi), IR remote control, and Modbus RTU rs485 support.
